Ehlke said that he couldn't be sure what caused the death of
2-month-old Gabriel Olson in August of 2011 even after all of the medical and
scientific testimony in the case.

Earlier, Olson pleaded guilty to second-degree reckless
homicide. The defense argued Olson had
been drinking, fell asleep on the couch, woke up and picked the baby up, then tripped
and fell on top of him.

According to the State Journal, the child's death was
attributed to multiple head and abdominal injuries, which included skull and
rib fractures.
